Looks like you had a more successful bluebell hunt than me. There are plenty just about ready to go in Brinscall Woods and Roddlesworth Woods too, from the look of things this morning, but they're largely under the woodland canopy, so I think they're running a week or two behind those that are out in the open.
I don't know if this is something I've ever seen before, it's not a plant I'm familiar with. I'll have to keep my eye out for it the next time I'm pottering around in the woods. What sort of habitat does it tend to prefer?
